<p>{W}e investigate the computational structure of a paradigmatic example of distributed social interaction: that of the open-source {W}ikipedia community. {W}e examine the statistical properties of its cooperative behavior, and perform model selection to determine whether this aspect of the system can be described by a finite-state process, or whether reference to an effectively unbounded resource allows for a more parsimonious description. {W}e find strong evidence, in a majority of the most-edited pages, in favor of a collective-state model, where the probability of a “revert” action declines as the square root of the number of non-revert actions seen since the last revert. {W}e provide evidence that the emergence of this social counter is driven by collective interaction effects, rather than properties of individual users.</p>
